President Obama sits in the famous Rosa Parks bus at The Henry Ford

In Detroit for a fundraiser, President Barack Obama took a side trip to The Henry Ford museum and visited the restored Montgomery, Ala., city bus where Rosa Parks refused to give up her seat in 1955, sparking the civil rights protests that would eventually end Jim Crow laws. Parks' seat in the General Motors coach was the one across the aisle from the president -- a distance of a few feet that spans 56 years of revelatory changes.
